Which sign may indicate that a customer is intoxicated when observing their walking?

The indication that a customer is intoxicated can often be observed through their physical behavior and coordination, particularly in how they walk. A person who is off-balance while walking demonstrates a lack of coordination and stability, which are common signs of intoxication. Alcohol can impair motor skills, making it difficult for individuals to maintain their balance, leading to swaying or stumbling.

In contrast, walking straight without stumbling or maintaining a quicker pace typically suggests better coordination and control. Additionally, simply looking around while walking does not necessarily correlate with intoxication; it could just mean that the person is aware of their surroundings. Therefore, off-balance walking is a clear sign of possible intoxication and should raise concern for server or seller staff regarding the patron's condition.
